My old hard drive crashed on my Mac but I was able to pull off some files. It's still accessible as an external as long as I don't pull off large files. I have a pdf document that I edited in CS4 (maybe acrobat 8?) Now when I try to edit it I don't have permission. Is there a folder I can copy over with permissions or a way to over ride the permission settings so I can edit the PDF and not have to retype the whole thing?
